Abstract

The invention discloses an automobile seat head restraint bone frame faciliating height adjustment, which comprises a rod body and a mounting adjustment device cooperated with the rod body, wherein the rod body is n-shaped and comprises a left rod and a right rod which are parallel to each other; The adjusting device comprises a mounting base body, wherein a button, a first locking plate and a second locking plate are slidably mounted in the mounting base body along the length direction of the mounting base body, and the button has a first unlocked state and a second unlocked state within thetravel range of the button body; In the first unlocked state, the button pushes the first locking plate to move, and the lever body can move up and down relative to the adjusting device; In the secondunlocked state, the button pushes the second locking plate to move and the lever body can be disengaged from the adjusting device. The technical effect of the invention is that the two-stage unlocking can be realized by applying different pressing force to the button, the height of the head restraint can be adjusted, and the head restraint can be completely taken out when necessary.

Description

technical field [0001] The invention relates to a car seat component, in particular to a car seat headrest frame which is convenient for height adjustment. Background technique [0002] Car headrest is a kind of driving comfort configuration product and safety protection product. It belongs to one of the national automobile compulsory certification and testing items. There are strict regulations on material, strength, energy absorption, position and size. In the current national standard, it is only stipulated that the front seat of the car is equipped with a car headrest. [0003] Among them, the headrest includes an adjustable type, which mainly refers to the ability to adjust in the height direction to meet the needs of drivers of different heights. In terms of the height adjustment function of the existing headrest, the height adjustment of the headrest is mainly realized through a single-stage unlocking method. Such an unlocking device cannot ensure that the headrest c...
